An investigation is underway after a man in Des Moines, IL shared a meme of Rep. Frederica Wilson that seeks help in lynching the Florida Democrat.

Police in Des Moines have handed the investigation over to the FBI, who are also working with US Capitol Police.

The suspect, Tom Keevers, says he didn't send the meme, which depicts Wilson and reads: "Need ten good men to help carry out a lynching. Must have own horse and saddle. Rope will be provided."

However, the post included a photo of Keever, his name, and a location stamp. Keever told the Chicago Tribune that a "meme-maker" put words into his mouth and now he and his family are being threatened.
